Researchers from the GenX Exposure Study detected PFAS originating from a fluorochemical manufacturing plant—including Nafion byproduct 2 and GenX—in nearby private wells in Bladen and Cumberland Counties, N.C. PFAS refers to a group of chemicals.....»»
New large stellar flare detected from EV Lacertae
Astronomers have performed multiwavelength observations of a nearby M-dwarf star known as EV Lacertae (or EV Lac for short). The observational campaign resulted in the detection of a new large stellar flare from this object. The finding was detailed.....»»
"Blob-like" home of farthest-known fast radio burst is collection of seven galaxies, researchers find
In summer 2022, astronomers detected the most powerful fast radio burst (FRB) ever observed. And coming from a location that dates halfway back to the Big Bang, it also was the farthest known FRB spotted to date......»»
Nvidia’s G-Sync Pulsar is anti-blur monitor tech aimed squarely at your eyeball
Branded monitors can sync pixels to backlighting, refresh rate, and GPU frames. Enlarge / None of this would be necessary if it weren't for your inferior eyes, which retain the colors of pixels for fractions of a second longer th.....»»
Scientists flip around gravitational-wave data analysis: Have LIGO and Virgo detected a merger of dark-matter stars?
Gravitational waves are ripples in the fabric of spacetime that travel at the speed of light. These are produced in some of the most violent events in the universe, such as black-hole mergers, supernovae, or the Big Bang itself. Since their first det.....»»
Researchers investigate pulsations of the ultra-luminous X-ray pulsar M82 X-2
Using NASA's Chandra spacecraft and ESA's XMM-Newton satellite, Chinese astronomers have inspected the pulsations of an ultra-luminous X-ray pulsar known as M82 X-2. Results of the study indicate that the pulsar showcases a long-term spin-down trend......»»
Pulsations detected from the XZ Ursae Majoris system
Astronomers have conducted a photometric and spectroscopic study of an Algol-type binary, known as XZ Ursae Majoris (or XZ UMa for short). Results of the study, presented in a paper published December 21 on the pre-print server arXiv, indicate that t.....»»
First pulsar detected in globular cluster GLIMPSE-C01
Using the Karl G. Jansky Very Large Array (VLA), astronomers have discovered a millisecond pulsar in the globular cluster GLIMPSE-C01 as part of the VLA Low-band Ionosphere and Transient Experiment (VLITE). This is the first pulsar ever detected in t.....»»
Astronomers detect new pulsar wind nebula and its associated pulsar
Astronomers from the Western Sydney University in Australia and elsewhere report the detection of a new pulsar wind nebula and a pulsar that powers it. The discovery, presented in a paper published Dec. 12 on the pre-print server arXiv, was made usin.....»»
Viruses as important factors driving the diel dynamics of marine bacterioplankton
The diel cycle is one of the most common periodic patterns in marine ecosystems. Previously, the diel rhythm changes of marine bacterioplankton have often been attributed to factors like bacterial light-dependent physiological mechanisms or their int.....»»
3D material found to break down antidepressant that contaminates water bodies worldwide
An study published in the Chemical Engineering Journal describes a strategy to produce a material based on zinc oxide (ZnO) capable of degrading sertraline, an antidepressant that has been detected, like other drugs, in groundwater worldwide and is c.....»»

Second radio relic discovered in the galaxy cluster Abell 2108
Astronomers from India and Taiwan have used the upgraded Giant Metrewave Radio Telescope (uGMRT) to perform radio observations of a galaxy cluster known as Abell 2108. As a result, they detected a second radio relic, which is much larger and differs.....»»
MongoDB corporate systems breached, customer data exposed
Database management company MongoDB has suffered a breach: attackers have gained access to some of its corporate systems and customer data and metadata. The MongoDB breach “We detected suspicious activity on Wednesday (Dec. 13th, 2023) evening.....»»
Ancient stars made extraordinarily heavy elements, researchers find
How heavy can an element be? An international team of researchers has found that ancient stars were capable of producing elements with atomic masses greater than 260, heavier than any element on the periodic table found naturally on Earth. The findin.....»»
Unlocking a climate puzzle: Study reveals hidden physics in quasi-linear temperature-radiation link
Curious about what drives Earth's climate sensitivity? A recent study in Advances in Atmospheric Sciences explores the complex links transforming the relationship between surface temperature and outgoing longwave radiation (OLR) from quartic to quasi.....»»
